APPARATUS FOR CLEANING TEXTILE THREADS.

Application filed April 14, 1924, Serial No.

My invention relates to improvements in apparatus for cleaning textile threads,.and more particularly in apparatus of the type in which the thread is pulled through an '5 aperture made in a plate so that the impurities are removed by the edges of the aperture.- I have found that by apparatus of this class such as are now in use and in which the aperture is in the form of a slot the threads 1 are not sufficiently cleaned. The object of the improvements is to provide an apparatus by means of which the impurities are tho-roughly removed, and with this object in view my invention consists in providingthe cleaning apparatus with a polygonal aperture so that the thread is engaged by more than two edges, the aperture being prefer ably provided by two members one containing a radial notch and the other one a smooth face closing the notch to form the polygonal aperture.

For the purpose of explaining the invention an example embodying, the same has been shown in the accompanying drawing in which the same reference characters have been used in all the views to indicate cor-i responding parts. In said drawing Fig. 1 is a section taken on the line AB ofFig.2, Fig. 2 is a section taken on the line C-D of Fig. 1,

Fig. 3 is a top plan view, Fig. 4: is an elevation ofa part of the apparatus,

Fig. 5 is a partial elevation looking from the left in Fig. 4, and r b Fig. 6 is an elevation of the notched mem- The apparatus is disposed on an angular 40 bracket a made integral with a slotted ear a for securing the same to a twistingmachine. The bracket is in the form of an open ring a having a sleeve 0 clamped therein by means of a screw 6, and in the sleeve an axial pin d is shiftable. On the sleeve a drum 6 is rotatable which is locked as against axial displacement by an annular spring 9 engaging in a groove 7 of the sleeve 0 and in a groove h of the drum. At its 9 end faces the drum is formed with triangular notches 2', the depth of successive notches increasing in increments of about .1 millimeter, figures provided at the side of each notch indicating the depths of the notches in tenths of a millimeter. On a reduced portion d of the pin d a drum 7c is loosely 708,594, and in Switzerland April 25, 1923.

mounted which shows a flange Z located at the side of the drum 6. The annular end face of the said flange is ground smooth and makes contact with the drum 6 so as toclose the notches i to provide therewith triangular apertures. Furthermore by means of the nut m a casing of porcelain is secured to the pin (1 which partly covers the drums c and k and is equipped at its upper extremity with a hollow thread guide 79 and at its side with an ear 0. The casing has two opposite shoulders m and :0 corresponding to the positions of the apertures for leading the threads into or out of the drum. To prevent accidental rotation of the drum 6 a nose 9 is formed on the bracket a engaging in any one of notches 1" provided at opposite sides of the drum 6. The casing n is locked as against rotation by means of a pin 8 secured to the bracket 06 and engaging in the bore of the thread guide.

The thread 8 to be cleaned is passed over the thread guide and passed through one of the notches i and a notch 7" and between the drums e and la, the attendant selecting the Y slightly pulled to the right and rearwardly,

so that it engages between the said drums and on the shoulders m and m of the casing n, whereupon it is automatically shifted by the spring into the aforesaid path after releasing the button u. The ear 0 is made use of only when inserting the thread. When thus inserting the thread a large partof its circumference is engaged by edges for stripping off the impurities which are therefore entirely removed.

The cleaning apparatus described herein can be used for threads of different thicknesses, the notches 5 corresponding each to a specific thickness of the threads. The drum 6 is provided at both faces with a suitable number of notches c' of different size and an equal number of notches 1" which are equal in size. Before inserting the thread to be cleaned the drum e isturned so that the notch i of the proper dimension is in the upper position and exactly below the shoulder a: and above the shoulder :0 so that the thread passes through the apertures without being bent. For locking the drum in set position one of the notches 9* provided at the opposite side of the drum 6 is engaged by the lug q.

Should the notches 2' provided in one. end face of the drum 6 be worn the drum 0 is turned around so as to bring the notches of the opposite face into operative position.

To permit dismounting of the'apparatus without any tools the drum 6 is pressed against the drum 7: by a spring 1.. The spring 6 bears on the button a bearing on an enlarged portion 1) of the pin (Z. The button it shows a radial slot to broad enough to permit the reduced portion (Z of the pin cl to pass therethrough when pushing the button u inwardly and removing the same in lateral direction. After thus dismounting the button the spring t is removed to the left in Fig. 1 and the pin (Z to the right.

Vhile in describing the invention reference has been made to a particular example embodying the same I wish it to be understood that my invention is not limited to the construction shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.

For example I do not limit myself to a construction in which the notches r are provided in a pair of drums.

I claim r 1. An apparatus for cleaning threads, comprising a pair of coaxially mounted laterally contacting circular members forming an aperture of polygonal form between the same, and a spring pressing said members together, said members being relatively displaceahle against the action of said sprin 2. An apparatus for cleaning threads, comprising a support, a rotatable drum and an abutting membermounted on said support coaxially and with adjacent end faces in contact with each other, said drum being formed at both sides with angular notches of different depths and with notches between neighboring angular notches, and the abutting member having a plane face adjacent to the drum, said support having :1 lug in position for locking engagement with any one of the notches of the drum intermediate the angular notches.

3. An apparatus for cleaning threads, comprising a support, a spindle mounted on said support, a rotatable drum and an abut ting member bot-h mounted on said spindle with adjacent end faces in contact with each other, said drum being formed at both sides with angular notches of different depths and with notches between neighboring angular notches, and the abutting member having a plane face adjacent to the drum, said support having a lug in position for locking engagement with any one of the notches of the drum intermediate the angular notches.

l. An apparatus for cleaning threads, comprising a support. a spindle rcn'iovabl v mounted on said support, a rotatable drum and an abutting member both mounted on said spindle with adjacent end faces in contact with each other, said drum being formed at both sides with angular notches of different depths and with notches between neighboring angular notches, and the abutting member having a plane face adjacent to the drum, said support having a lug in position for locking engagement with any one of the notches of the drum intermediate the angular notches, and a casing fixed on said spindle and enclosing said drum and annular member and having shoulders for guiding the thread.
